Detail

Vertical cast-in-place drilling roll is a kind of roll. The rolled steel grade is the key element for selecting the roll. Its deformation resistance changes with the chemical composition of the blank, which is mainly reflected in the load and change of deformation in each stage of rolling. It is necessary to select the roll according to the confirmed strength and hardness.




There are many kinds of rolling mills producing long products. Therefore, the selection and layout of rolling mill type, the selection of roll raw materials and the determination of roll size.




The distribution of roll stress along the roll body is uneven and constantly changing. The reason is not only the planning elements, but also the continuous changes of roll wear, temperature and roll shape. In addition, rolling conditions are often abnormal. If the roller is cooled improperly after use, it will also be damaged by thermal stress. Therefore, in addition to wear, the roll often presents various partial hazards and surface hazards such as crack, fracture, falling off, indentation and so on. A good roll should have a better match between its strength, wear resistance and other performance indexes. In this way, it is not only durable under normal rolling conditions, but also less harmful in some abnormal rolling conditions. Therefore, when making rolls, we should strictly control the metallurgical quality of rolls or supplement external measures to enhance the bearing capacity of rolls.
